libvirt: ignore NOSTATE in resume_state_on_host_boot() method.
libvirt: ignore NOSTATE in resume_state_on_host_boot() method.

Occasionally, libvirt would get NOSTATE from hypervisor as instance
state. Thus if we don't ignore instances in NOSTATE in
resume_state_on_host_boot() method, we would mistakenly reboot such
instances when we restart nova-compute service or on host boot. This
patch fixes this by adding NOSTATE into ignored_states.
